ABSTRACT:
Ski apparatus two outer skis coupled to a third ski, located between the two outer skis, by four cranks, connected as a front pair and a rear pair. Each crank has a gear on one end and a free end. The free end of a crank is attached to a journal box on an outer ski to permit the crank to rotate freely. The gear of the crank from one outer ski meshes with the gear of a crank attached to the other outer ski, coupling the cranks in pairs and causing the cranks to rotate in opposite directions. The gears from each pair are contained in a gearbox attached to the third or middle ski. The cranks can be stiff or resilient and, if resilient, includes an elbow joint which is spring biased to force the middle ski below the outer skis.
